ATTORNEY v 3' rawijiiiioaes, ivjI'e Atlas'--Mineral"- Pairsem rm This invention relates gaiierallyto anaim oved method of constructing-tanks,.and particularly tanks usedin. the pickling :processaoi stock-treats mena, .,i @19 Methods heretofore jused. in. :the construction .of tanks ofv this character havenot been entirely successful, as breaksioocur. at certainapoints i in the bonding materials/1 The methods referred to usually include the laying; of bricksor vitrified blocks with bonding includi-ng sulphur compounds, the: practice being to -lay I1 successive courses of blocks, and: to: pour-the bonding oompound. at the completion of each courserv-y'l'hese alternatedaying' and: bonding loperations: cause imperfect cohesionsoi the bonding: materials, beicause of the fact that'by thez-i-time the second pour is madethe'. prei-teding: pour-has become cooled ftoa such :extent as to prevent lalproper cohesion or the twoxbondsn :In most instances delays occur in the completion of the: entire tank, so that. upon resumption of work, the hot materials will not properly cohere with the cold bond previously made. In instances such as these, uneven contractions and expansions occur,

preventing proper bonding and usually resulting in breaks wherever such improper associations of materials have been made.

The present method contemplates the erection of tanks with materials identical with those here-I tofore employed, but in such manner as to retain a substantially constant temperature until the entire structure is complete.

The invention will be best understood by reference to the following detailed description and the accompanying drawing disclosing the improved process, and wherein:

Fig. 1 is a transverse sectional view taken through a base and wall erected in accordance with my improved process,

Fig. 2 is a. top plan view,

Fig. 3 is an end view of the base and wall "after the stripping process,

Fig. 4 is an enlarged side elevation of a part of the wall and showing the means for supporting the blocks or bricks, and ready for the pouring operation, and I Fig. 5 is a fragmentary vertical sectional view taken through a wall showing a slight modifica tion.

Referring now more particularly to the draw-' ing, 6 indicates a base or floor for the tank, which may be formed of vitrified blocks or bricks. A wall of the tank is indicated generally at 'l, and it will be understood that this wall rests upon and extends entirely around the base or bottom a as to ropeilyl' retain --the pickling or other i icai to retairid withinthe tank..- n

I

In the erection of the walls, the lower course of bricks is laid andmaintained properly spaced from each other upon the supporting foundation. The walls arelaid between thicknesses 8 of sheet material, within a chamber provided between parallel upstanding forms 9 spaced a substantial distance beyond'the sides of the wall blocks. A

, packing of insulatingmaterial 10 fills the spaces between the forms 9 and the next adjacent sheet 8, which insulating material may be sand, sawdust, cork or the like. Upon setting of the lower course of the wall, the hot bonding agent is poured, filling the spaces between the blocks and passing through to cohere with the'hot bonding agent of the underlying base.

The courses of the walls are laid and poured successively, while the forms 9 and packing material are correspondingly erected. In other words, the leg of the wall progresses simultaneously with the up buildingof the forms and the insertion of packing so that a substantial uniform wall temperature is retained throughout the height of the wall. In order to facilitate this operation, the forms will be made in sections.

In preparing a course of blocks for pouring, the several blocks of the course are laid upon chips 11 of bonding material as shown in Fig. 4, which, when the hot material is poured, will melt or dissolve and will cohere with the bonding agent. After the base and the several courses .wall sides.

where a continuous metallic plate is to cover.

the exterior surface of the wall, thisplate will take the place of the exterior paper sheet8. It

will be understood that the sheetsBprevent the hot bonding material coming in contact with theinsulating material, as well'as to properly define the mold within which the bricks or blocks are laid. I

By erecting a structure in the manner described, it is apparent that a substantially even or constant wall temperature is obtained, as dissipation of. the heat of the bonding material will be prevented by the insulation upon each of the In erecting the tank in accordance with my method, it; must be understood that com-- pletion of the work at one time is essential, as to allow thev wall to become coldand then .resume layingand pouring operations wouldciefeat the objects of the invention. It has been found that by erecting tanksyin; the manner described, breaks or cracks in the bonding agent do not occur, and the objections common to the processes heretofore employed are entirely overcome.

Having thus described my-invention, I claim:- 1.
